Please read these instructions carefully before beginning the assembly. Failure to understand and
follow assembly instructions may result in injury to technician and/or end user and may void the
warranty. If you have any questions call Sunrise Medical Technical Support at [phone].
Before beginning the shroud replacement,
ensure you heed the following warnings.
WARNING
Minimal electronics experience is required to
complete Shroud Replacement.
WARNING
Ensure your work surface is free of any build up
of liquids and/or static electricity. Touch a metal
surface to discharge static electricity prior to
touching the PCB (Printed Circuit Board).
WARNING
Limit touching of the PCB to outer edges with as
light a touch as possible, minimizing pressure on
the PCB.
WARNING
If the PCB must remain outside of the enclosure,
place it in a static protective bag until ready for
reassembly.
WARNING
Attach the ground cord from the ESD
(Electrostatic Discharge) Field Kit to the
uncoated metal shown in Figure 1. Follow all
instructions provided in the ESD Field Kit to
ensure not to damage the PCB.
1. To remove skid plate (B), use an M2 Allen
wrench to remove screws (A). (Fig. 1)
2. To remove battery plate hardware, use
a T-20 t-handle to remove torx screws (C)
and loosen the battery plate (Fig. 2)
3. To loosen PCB mounting hardware, use a
T-15 t-handle to loosen screw (D). (Fig 3)
4. To remove hardware on side of shroud, use
a T-20 t-handle to remove screws (E).
(Fig. 4)
5. To remove hardware on front of shroud,
use a M4 Allen wrench to remove socket
head screws (F). (Fig. 5)
6. To remove the left shroud, disconnect the
charger port harness (G). Then, remove the
shroud. (Fig. 6)
Note: If replacing the left shroud only,
reverse the order of steps 1-6 to fit the new
left shroud. Before tightening the hardware
ensure you line up the shroud and the PCB,
fitting the PCB into the shroud slot (H).
(Fig. 6)
Tools required
1. Allen wrench, sizes: 2mm, 4mm
2. Flat head screw driver
3. T-handle, sizes: T-15, T-20

7. To remove the PCB (K) from the
right shroud, loosen the screw (L).
(Fig. 7)
Note: for reassembly, ensure screw
is aligned with PCB mounting hole.
8. Disconnect the connectors from
the top of the PCB (Fig. 8). Pull the
9-Pin connector from the motor
(Fig. 9) through the right shroud
before disconnecting. Ensure the
motor harness stays on the outside
until the PCB is reconnected.
9. Disconnect the connectors (I) from
the bottom of the PCB (Fig. 9) and
remove the battery plate (J)
(Fig. 7).
10. Remove the wire grommet (M) on
the shroud using a flat head screw
driver. (Fig. 10)
11. To remove right shroud front
hardware, use a M4 Allen wrench
to remove socket head cap screws
(N). (Fig. 11)
12. To remove right shroud, pull the
harnesses for the motor (O), the
actuator (P), and switch (Q)
through the shroud. (Fig. 12)
13. Ensure you note the orientation of
the PCB shown in Fig. 8 and Fig. 9
before reinstalling the PCB.
Incorrect installation will result in
damage to the PCB. You will need
to connect the motor connector
from the PCB first. Then, push the
motor connector back through the
hole in the right shroud.
14. Connect the motor connector from
the PCB first. Push the motor
connector back through the hole in
the right shroud.
15. Connect the connectors on the
top of the PCB (Fig. 8). Connect the
connectors from the battery plate
(J) to the bottom of the PCB
(Fig. 9). Reconnect the connector
from the charger port (G) (Fig. 6) to
the battery plate (J) (Fig. 7).
16. Replace the right shroud by
following steps 10-12 in reverse.
